N2YO is giving you the AOS time for. your location -- assuming you have it set up properly. ARISS is giving the time for the contacting ground station. I'm not sure how much time ARISS schedules after AOS to begin the contact. -- Mark D.

Are the questions for Tuesday's ISS School contact posted somewhere or possibly a live feed?
Also, I had noticed last week that the beginning of contact time as predicted on N2YO.com was about 4 minutes earlier than the ARISS bulletin had it. Now that it's a few days later, N2YO has an updated AOS time that is much closer to the time on ARISS which hasn't changed. I originally assumed that N2YO would be more accurate than the time posted on a static timeline, but now I'm wondering if ARISS has more insider details than are available from the public TLEs or if N2YO was just using an older data source.
